Hello,
I am trying to control SG90 servo with PCA9685 and banana pi m2 ultra. I don’t know how to access PCA9685 pins with gpio pins. I powered PCA9685 with 5V, and here is my connection: PCA9685 -> Banana pi m2 ultra VCC pin 1 (3.3 V) SDA pin 3 (SDA) SCL pin 5 (SCL) GND pin 9 (GND)
I have 3 SG90 servo; they care connected on 0, 1, 2 respectively on PCA9685.
Thank you
